What I claim is:

.1. A valve comprising a metallic valve plate having a conical extension depending therefrom, a conical shaped valve with a flange flush with the perimeter of the valve plate and the whole bearing directly against the valve plate and composed of phenolic condensation material, the phenolic condensation material cooperating with the valve plate and the'conical extension to form the valve and attach the valve tothe valve plate.

2. A valve comprising a metallic valve plate having a conical extension de ending therefrom with a slot in the base of t e cone, a conical shaped valve with a flange flush with the perimeter of the valve plate and composed of phenolic condensation material molded about the conical extension and hearing directly a ainst the valve plate to prevent leakage from the valve plate through the valve.

3. A valve comprising a metallic valve plate havinga conical extension depending therefrom, a conical shaped valve flush with the perimeter of the valve plate and the whole bearing directly against the valve plate and composed of phenolic condensation material, the phenolic condensation material cooperating with the valve plate and the conical extension to' form the valve and attach the valve to the valve plate.

4. A valve comprising a metallic valve plate having a conical extension depending therefrom with a slot in the base of the cone, a conical shaped valve flush with the perimeter of the valve plate and composed of phenolic condensation material molded about the conical extension and bearing directly against the valve plate to prevent leakage from the valve plate through the valve.
